SUPERCHARGER COUPLING
First Claim
1. A rotational element coupling device in a supercharger, comprising:
- a rotatable output shaft having tapered external splines and an output shaft axis of rotation;
a coupling disk having;
a disk axis of rotation coaxial with the output shaft axis of rotation;
a tapered internally splined bore coaxial with the disk axis of rotation to engage the tapered external splines; and
a plurality of disk apertures defined in the coupling disk parallel to the disk axis of rotation;
a plurality of pins each having a disk end and a timing gear end distal to the disk end, the plurality of pins matingly engaged with the coupling disk at the disk end of the pins via the plurality of disk apertures; and
a timing gear fixed to a supercharger rotor for rotation therewith, the timing gear having;
a timing gear axis of rotation; and
a plurality of timing gear apertures disposed in the timing gear and matingly engaged with the timing gear end of the plurality of pins.

Abstract
A rotational element coupling device in a supercharger includes a rotatable output shaft having tapered external splines and an output shaft axis of rotation. A coupling disk has a disk axis of rotation coaxial with the output shaft axis of rotation, a tapered internally splined bore coaxial with the disk axis of rotation to engage the tapered external splines, and a plurality of apertures defined in the coupling disk parallel to the disk axis of rotation. A plurality of pins each have a disk end and a timing gear end distal to the disk end. The plurality of pins matingly engages with the coupling disk at the disk end of the pins via the plurality of apertures. A timing gear is fixed to a supercharger rotor for rotation therewith. The timing gear has a plurality of apertures disposed therein to matingly engage with the timing gear end of the plurality of pins.

9. A method of making a supercharger, the method comprising:
-
disposing in a supercharger housing a rotatable output shaft supported by bearings, the rotatable output shaft having tapered external splines and an output shaft axis of rotation; pressing a coupling disk on the rotatable output shaft, the coupling disk having; a disk axis of rotation coaxial with the output shaft axis of rotation; a tapered internally splined bore coaxial with the disk axis of rotation to engage the tapered external splines; and a plurality of disk apertures defined in the disk parallel to the disk axis of rotation; disposing in the supercharger housing a rotor assembly having a rotor shaft disposed therein; disposing a timing gear on the rotor shaft, the timing gear having a timing gear axis of rotation and a plurality of timing gear apertures disposed in the timing gear; and coupling the timing gear to the coupling disk via a plurality of pins, the plurality of pins each having a disk end and a timing gear end distal to the disk end, the coupling being accomplished by; matingly engaging the plurality of pins with the coupling disk at the disk end of the pins via the plurality of disk apertures; and matingly engaging the plurality of pins with the timing gear at the timing gear end of the plurality of pins via the plurality of timing gear apertures. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
